Pointers in The C

Ninnat Aupala, 2015. — 100 p. — ASIN: B00TI9GAA8When a variable is defined in a C program, the compiler will find and allocate unused locations in memory to that variable to use. Since the area of memory consist of a lot of cells, each cell is identified by a unique number called its memory address (or, for short, that address), to distinguish it from the other cells in memory. Every memory cell has one byte in size. So to access the desired memory location, the address of that location is needed.
